Detection of polymorphic malware variants plays an important role to improve information system security. Traditional static/dynamic analysis technologies have shown to be an effective characteristic that represents polymorphic malware instances. While these approaches demonstrate promise, they are themselves subject to a growing array of countermeasures that increase the cost of capturing these malware...
Application of virtual reality to tour guide training makes it possible to change the conventional teaching model into the communicative task-oriented one. The study describes the development and implementation of virtual reality in tour guiding to improve communicative skills and professional knowledge of tour guide candidates.

Mobile Ad hoc network is a self-organizing, multi-hop and wireless network. This kind of networking is convenient to construct because it is free of time and space and it can be constructed without infrastructure. It has been widely used on many occasions such as danger zones, military regions, hospital and family. Due to the dynamic changes of topology, Ad hoc network has its particularity of routing...
This paper analyzes the deficiency of the average queue calculation in tradition RED queue, and presents a calculation algorithm for the calculation of RED's average queue based on the current network conditions in order to enhance the self-adaptation of RED and we use NS2 for the simulation. Experimental results show that the improved RED performances better than tradition RED in the middle congestion...
